Controlling Extraneous Variables in Research Coursework - 2

Controlling Extraneous Variables in Research - Coursework Example They do it based on the rational analysis and past occurrence. After spotting the extraneous variables, they can be regulated through grasping a variable steady. Another way of controlling the extraneous variables is through building a consistent environment and system to ensure that all variables are equal in every condition. Researchers have also embarked on random assignments where a group of researchers takes part in the same research. In random research, different researchers or groups are assigned to perform the task where a mathematical theory is applied to conduct the research. Â  In the article, a hypothetical construct has been identified as an extraneous variable, it is not seen directly. However, there are dimensions that have been formed to help learn hypothetical constructs in a more systematic way. Researchers use different techniques to address the issues related to the extraneous variables such as standardization that is mostly used in survey analysis. Researchers also ensure those extraneous variables are kept the same for all the research parts. It also requires the researchers to be aware of the extraneous variable especially throughout the design phase and be able to control it. Balancing the variable across the research stages also reduce the chances for the influence of the research by an extraneous variable. The balancing enables comparison between the research groups and stages.
